In the new scientific research, cognitive psychologists and friends from Leiden University in Spain completed two tests on 32 participants aged 18~26. In the first test, participants drank 400 ml of orange juice containing tyrosine. In the second test, participants drank orange juice with placebo effect. After drinking drinks, participants were asked to explain divergent thinking problems. The test results show that participants' ability to answer questions after drinking orange juice containing tyrosine is significantly better than that after drinking orange juice containing placebo effect.
The analysis emphasizes that tyrosine can promote the metabolism of a large amount of choline in human brain, which is conducive to improving innovative thinking and working ability. Eating ingredients containing tyrosine is a good choice to improve logical thinking ability. In addition to fresh fruits such as iPhone and banana, soybeans, spinach and eggs also contain tyrosine.
